Problems solved by technology

As the intensity of the ion beam increases, the nonlinear space charge effect of the ion beam becomes stronger during acceleration, and the ion beam is prone to divergence and loss, resulting in frequent high-voltage ignition of the accelerating tube.

At the same time, when the ion beam is accelerated, the stray ions will hit the insulator wall of the accelerating tube and the accelerating electrode to generate a large number of secondary electrons, which will damage the insulation performance of the accelerating tube and easily lead to high-voltage breakdown of the accelerating tube, thus limiting the intensity of the ion beam and energy boost
